New Delhi, Nov. 3 -- Congress leader Rahul Gandhi at a poll rally in Bihar's Begusarai on Sunday said that if the Opposition grand alliance, or Mahagathbandhan, comes to power, the government would work for the most backward classes, backward classes, minorities as well as the poor from the general castes. Gandhi's assertion, according to a senior party functionary, sends two messages in the poll-bound state - it will not be a Yadav-dominated government; and the Congress will play a key role for social justice. As the battle for backward and Dalit votes intensifies between the ruling NDA and the Grand Alliance in Bihar, the Opposition bloc hopes that Gandhi and his latest brand of politics will appeal to Dalit and Extremely Backward Class (EBC) voters and pay electoral dividends. "Rahul Gandhi is best suited to bring Dalit votes and the EBC votes for the Mahagathbandhan. He has tirelessly fought for Dalits and he was the main leader to push for caste census. Gandhi also led the Mahagathbandhan to release a special Nyay Patra (charter) for the EBCs. All these steps have made him the most reliable leader for the EBCs and the Dalits," Avinash Pande, Congress general secretary for Uttar Pradesh, who is among the party's observers for Bihar, said. Ashok Bharti, chairman of National Confederation of Dalit and Adivasi Organisations (NACADOR), told HT that Gandhi has been able to "instil confidence among the Dalits and OBCs that he is serious about social justice and he is the best person in the Opposition to attract Dalit, Adivasi and Backward votes." Bihar has 38 reserved seats for Scheduled castes and two for scheduled tribes....
